Deimos, moon of Mars — where Lord Slaadek's plans to revive the ancient Ice Warrior civilization hang by a thread. Only the Doctor can stop him… but an old enemy, hiding in the catacombs, has an alternative plan, one that will test the Doctor's heroism to its limits. Just how far will the Doctor go to prevent the destruction and resurrection of Mars — on a day when his friends become enemies, and his enemies have right on their side?

The Monk claims that Halcyon has a population of 20 billion, yet their entire population has all that they could want. On their return to his TARDIS, the Monk takes them one year forward in time, at which time the Ice Warriors have destroyed all life on the planet to their attempt to create a second Mars. The Monk blames this on the Doctor's interference with the Ice Warriors' plans on the Deimos moonbase a thousand years earlier. The Doctor later describes it as one of the greatest catastrophes in the history of the universe but is powerless to prevent it as doing so would have major ramifications on the Web of Time.

The Doctor repairs the re-ioniser, which allows the Ice Warriors to destroy the passenger rocket and kill all 600 people aboard.

During the Monk and Lucie's travels together, they subsequently visited a planet called Questes which was ruled by a dictator, who according to Lucie was "like Genghis Khan but with two beards." In order to prevent him from being born, the Monk arranged for his parents (as well as dozens of other innocent people) to be killed in an avalanche. After Lucie objected to this since she viewed it as being murder, the Monk materialized his TARDIS on Deimos and threw her out. He knew that Lucie's presence would prevent the Doctor from destroying the moonbase.

The Monk tells the Doctor that he altered the settings on the Ice Warriors' suspended animation chambers to ensure that they awoke in the 23rd century, several centuries earlier than in the original timeline.

The Doctor detonates the explosive device placed in the moonbase by Grenville, leading to the facility's destruction. This results in the moon being converted into a miniature sun, which provides the necessary heat to power the atmospheric re-ioniser. He then uses the re-ioniser to terraform Mars so that its atmosphere is composed of 80% nitrogen and 20% oxygen. Consequently, the planet is made habitable for humans as was the intention of the scientists and engineers who designed the re-ioniser prior to the Great Recession. The Doctor claims that doing so was consistent with recorded history and therefore did not damage the Web of Time.

The Doctor discovers that Lucie was the Monk's accomplice "Brother Lucianus" at the Abbey of Kells while Lucie learns that the Doctor was the apothecary who was assisting "Sister Maria." (AUDIO: The Book of Kells)

The Doctor tells Lucie that he used to be "the man with a master plan" who arranged the destruction of his enemies and the toppling of dictatorships in order to serve the greater good to the point where he began to countenance sacrificing the lives of the few to save the many. (TV: Remembrance of the Daleks, et. al) He eventually began travelling on his own as he was no longer willing to risk the lives of his companions after an incident which he does not want to discuss. Following his regeneration into his eighth incarnation in San Francisco on 30 December1999, the Doctor abandoned these tendencies and vowed that he would never travel alone again as he did not want to forget how precious life is.

Originally launched as the "new" Eighth Doctor Adventures, Big Finish ultimately came to label these simply the "Eighth Doctor Adventures" on their official website. During the life of this range, the Eighth Doctor principally travelled with Lucie Miller. In the fourth series, he also had adventures with Tamsin Drew, his granddaughter, Susan, and her son, Alex.
